"O"-Jung.Ban.Hap.

"O"-Jung.Ban.Hap. (stylized as "O"-正.反.合.), sometimes referred to as "O"-Union or just O, is the third Korean studio album (fourth overall) by South Korean pop group TVXQ, released on September 29, 2006 by S.M. Entertainment. In a year when Korean music sales had slumped, it was the highest selling album in South Korea in 2006 and won the group several prominent awards in South Korea. The album stayed charted within the top 50 throughout 2007. By 2014, it sold over 475,000 copies.

The album's name "O"-Jung.Ban.Hap, literally translated to "O"-Justice.Opposition.Solution, is based on Georg Wilhelm Friedrich Hegel's theory of thesis, antithesis, synthesis. The album's mononymous lead single has lyrics that regard global conflicts with a plea for peace and resistance. The album has a balance of fast tempo songs and ballads.
